Flash-Messages in Symfony2 doesn't seem to work in my twig-template

Question

I want to add support for flash messages on our pages. I implemented this by following the documentation found here.

I added the following snipplet to my base layou

Answer 1

By symfony 2.6 +

{% if app.session.flashbag.has('notice') %}
    {{ app.session.flashbag.get('notice').0 }}

{% endif %}

Because flashbag is by this version array you need foreach it or use index. I m using index because i dont need something more.
